Warnings and Precautions
The AC68C Digital Clampmeter conforms to EN61010-2-032,
EN61010-1, CAT III- 600V, class 2 and pollution deg. 2; and
UL3111-1. It is recommended for use with local level power
distribution, appliances, portable equipment, etc., where only
smaller transient overvoltages may occur, and not for primary
supply lines, overhead lines, and cable systems.
•
Do not exceed the maximum overload limits per function
(see specifications) nor the limits marked on the
instrument itself. Never apply more than 600 V dc / ac
rms between the test lead and earth ground.
•
Inspect the DMM, test leads and accessories before
every use. Do not use any damaged part.
•
Never ground yourself when taking measurements. Do
not touch exposed circuit elements or test probe tips.
•
Do not operate the instrument in an explosive
atmosphere.
•
Exercise extreme caution when: measuring voltage
>20 V // current >10 mA // AC power line with inductive
loads // AC power line during electrical storms //
current, when the fuse blows in a circuit with open
circuit voltage >600 V // servicing CRT equipment.
•
Always measure current in series with the load – NEVER
ACROSS a voltage source. Check fuse first. Never
replace a fuse with one of a different rating.
•
Remove test leads before opening the case.
